Hinweise
Verwenden Sie diese, um dem TextWordNode-Objekt Ihre eigenen Daten hinzuzufügen.
Beispiele
Im folgenden Beispiel wird einem InkAnalyzer (theInkAnalyzer) ein TextWordNode-Objekt für ein TextBox-Steuerelement (theTextBox) hinzugefügt. Die Position des TextBox-Steuerelements wird von Pixelkoordinaten in Freihandkoordinaten konvertiert. Die Data-Eigenschaft des TextWordNode-Objekts wird als Text-Eigenschaft des TextBox-Steuerelements festgelegt.
